Efficiency "green" lamps significantly higher efficiency "bulbs Ilyich. Do compact fluorescent lamps (CFL) 25% of electricity consumed goes to the production of light, the light-emitting diode, led (light emitting diode – Light Emitting Diode) and oled (organic light emitting diodes), even more – 80%. Compact fluorescent lamps have appeared in the late 1980's. They significantly outperform the "old" lamp as in luminous efficiency, and on service life. If the average lifespan of incandescent bulbs – 1,000 hours, then the cfl this figure reaches 15,000 hours. However, there is a fluorescent lamp and its drawbacks. They did not immediately come to full brightness and are not intended for frequent on-off.

In addition, these lamps contain mercury. And if Europe There is a developed network of reception of spent fluorescent lamps, in Russia, the question remains open for recycling. led lamps have been used in general lighting is not so long ago. For a long time on the market were not are white LEDs, because so far there is no semiconductor material to directly create white light. But scientists have found the solution: a mixture of complementary colors or fluorescent transformation. led lamps more efficient than fluorescent, but their service life can reach up to 100,000 hours. LED-lamps contain no mercury, making them environmentally friendly. However, LEDs are still quite expensive and not have high capacity. But, experts say, the achievement of optimal parameters – just a matter of time. Presumably in three to five years, the cost of led lamps will be reduced significantly.

STOP smoking think that I am a person with great force of will, but in relation to tobacco seems I have none. I smoke about two packs of cigarettes a day and I’ve already tried to quit several times. However, addiction is stronger than me, since I have not been able to endure beyond a week. I’ve gone over and over again. Is there any effective way to quit this bad habit? Carmen Lugo Espana dear Carmen: surely know that your problem is quite common and that there is no single, simple, nor much less foolproof solution. The clarification, you discuss some ideas that could perhaps help you.

Firstly, it is important to have clear that the main obstacle when it comes to quitting is the psychological withdrawal, and not the physics. Physical abstinence, in reality, has a very mild intensity in comparison with other addictive substances and for a duration not exceeding the week. Then, does role smoking? This will surely be different for each person, but, in our opinion, there are three issues which, in the majority of cases, are linked to smoking. For this reason, it is essential to discover which of them have more weight for you. The first is that cigarette often facilitates included in sociales situations, gives a sense of belonging or conveys an image that we assume desirable. The second issue is that smoking helps to better tolerate some downtime. It is a quite frequent complaint among those who abandon smoking, that there are many moments in that do not know what to do, spare them a time that makes them uncomfortable. The third mode that is often used cigarette is to calm anxiety. Vale clarify that, Yes, nicotine is not anxiolytic, rather the opposite. Smoking calm anxiety in the same way that any repetitive behavior makes it as eating or cleaning.
